2 Minutes is actually a real Blitz game. 1 minute of thinking time to conjure up the strategy, 1 minute to checkmate. 5 Minutes is a suitable balance if you ask me. I don't wanna play those 1 or 2 minute games, it goes by too quick and you don't really learn anything.

What I find when my clock starts running down is that the time it takes for your respected enemy to move and you are ready to move it takes about a second for your computer to register. I believe that 5 minutes are a good balance as well. Unless the people at FlyOrDie want to make another room (good forbide) and call it bullet chess it would be a good idea. But changing blitz is no good idea.
